Efficiency: Doing More with Less

Efficiency: Doing More with Less

Learning Objective

At the end of the lesson, you will be able to define efficiency in computer science, give examples of efficient algorithms, identify similar words to efficient, and recognize opposite words of efficient.

What do you already know about efficiency in computer science?

Definition of Efficient

Efficient in computer science refers to the ability of a system or algorithm to complete a task with minimal resources, such as time, memory, or energy.

Examples of Efficiency

Examples of efficient algorithms include sorting algorithms like QuickSort and searching algorithms like Binary Search.

Similar Words to Efficient

Similar words to efficient include effective, productive, and streamlined.

Opposite Words of Efficient

Opposite words of efficient include inefficient, wasteful, and ineffective.

Summary

Efficiency in computer science involves completing tasks with minimal resources. Examples of efficient algorithms include QuickSort and Binary Search. Similar words to efficient are effective, productive, and streamlined. Opposite words of efficient are inefficient, wasteful, and ineffective.

Interactive Activity

Provide students with a list of algorithms and ask them to identify whether each algorithm is efficient or inefficient.

Q&A Session

Allow students to ask questions or discuss any concepts they find challenging.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
